Crossroad lane setting and passing method

Abstract

The invention discloses crossroad lanes and a passing method. The passing method comprise setting of traffic signal lights and traffic markings, wherein the set lanes sequentially comprises a right-turn special lane, a left-turn special lane, a left-turn lane, a straight special lane, a straight lane and a right-turn lane from left to right; the right-turn special lane, the left-turn special laneand the straight special lane are reverse-driving lanes; pre-left-turn signal lights are arranged on positions where the straight special lane and the left-turn special lane are away from a front crossroad by a certain distance; a rear lane, corresponding to the pre-left-turn signal light, of the left-turn lane is a reverse-driving straight lane; a rear lane, corresponding to the pre-left-turn signal light, of the straight special lane is a forward-driving left-turn lane. When a car stops at a red lightlamp, no gaps of vehicles on each reverse-driving lane occur, and the car drives through thecrossroad lanes in a manner of matching corresponding traffic light control, so that a red light period is shortened, the vehicle passing quantity in the period is increased, the problem of a conflict of a left turning car and a straight driving car can be solved preferably, the traffic passing capacity of the crossroad is improved, and the traffic jam phenomenon of conventional crossroads is relieved.

Description

Technical field [0001] The invention relates to a lane setting and passing method, in particular to a crossing lane setting and passing method. Background technique [0002] With the rapid economic development and the rapid increase in vehicle ownership, traffic congestion is becoming more and more serious. Especially in my country, the traffic problem has become a serious problem that cities have to face. Traffic congestion has caused a great waste of time and energy; tradition The solution is to widen the road, but in fact the most likely place to cause traffic congestion is the road intersection, so widening the road cannot proportionally solve the existing traffic congestion problem. [0003] Existing road intersections mostly improve the traffic intersection capacity by setting different control times of signal lights, but the conflict between left-turning vehicles and straight-going vehicles passing at the same time cannot be fundamentally resolved by the method of close time ...

[0002] With the rapid development of the economy and the rapid increase of vehicle ownership, traffic congestion is becoming more and more serious. Especially in my country, traffic problems have become a serious problem that cities have to face. Traffic congestion has caused a great waste of time and energy; traditional The best solution is to widen the road, but in fact the most likely place to cause traffic congestion is the road intersection, so widening the road cannot solve the existing traffic congestion problem proportionally

[0003] Most of the existing road intersections improve the traffic capacity of traffic intersections by setting different control times of signal lights, but for the conflict between left-turn vehicles and straight vehicles passing at the same time, the method of close time interval control cannot fundamentally solve it. When the traffic flow is set to 6 vehicles per minute, the current traffic mode has a red light cycle of 2 minutes, and 12 vehicles will arrive at the intersection in that red light cycle. Under normal circumstances, 10 vehicles can pass through the green light within 30 seconds. There will be 2 cars stuck at the intersection, and if 2 cars are blocked in one cycle, 60 cars will be blocked at the intersection in that hour, which will cause a lot of traffic pressure
